Q: Will this detergent harm plants? Should plants be covered when applying the detergent?by Dennis from Virginia on April 23, 2015

A: No this is biodegradable and safe around plants. However I do recommend spraying down the plants first with water from your garden hose. This way they will definitely not be affected by the detergent. If not wet down first, sometimes the detergent can cause spotting.by Brian, Product Expert

No instructions on the bottle as to how much detergent to add per volume of water.

Peter,

I'm sorry you missed Line 12 of the Features for this product: "Your pressure washer will automatically dilute to the proper ratio",

You just put the siphon tube of your pressure washer into the bottle, or pour the detergent into your soap bottle; add your black Soap tip or twist your wand to the Mix position to apply soap. Pressure washers dilute on about a 1:10 ratio, so the 1 gallon bottle will provide 10 gallons of detergent.
